UX-13 P3: Simple view and Batteries screen

- Batteries: one card per battery with On/Off, the mode list (cheap hours
  and selling greyed out until OPT-11 P3), level, and Now / Today / Why
  lines built in homeview.py. Replaces the OPT-11 P1 minimal cards and uses
  the existing pack_use / pack_mode actions and store keys.
- An Off battery the peak limit still needs says so with its figure; no line
  shows 0 W beside moving power (OPT-11 P1 test F2). Today says "Not planned
  yet" until OPT-11 P3/P4.
- Home's plan leaves Off batteries out, except for the peak limit.
- Settings opens on Simple: the layout's simple fields with an applies chip
  and a note, plus the battery switches and modes. Installer is one tap.
- English and Dutch words in app/ui_text; test_batteries_screen.py; browser
  check tools/ux13_browser_check.py (CHECK=1 ux13_screenshots.sh); new and
  changed screenshots only.

No control, allocator, arbiter or command module changed.
